SPECIFICATION formingpart of Letters Patent No. 590,234, dated September21, 1897.

Application filed April 10,1897.

To all whom it may concern..-

Be it known that we, JAMES MOTURK and JOHN MCTURK, residing at Crystal,in the county of Tama and State of Iowa, have invented a new and usefulSpring-Axle,of which the following is a specification.

This invention relates generally to carriages and wagons, and moreparticularly to a sprin gaxle for such vehicles.

The object of our invention is to provide means for yieldinglycontrolling each wheel, so that when the wheel passes over anyobstruction or unevenness the usual jarring or tilting of the wagon willbe avoided. To accomplish this object we divide the axle, so that eachwheel is on a separate axle, and fix an arm on each section of axle andyieldingly connect it with the wagon-body bolster; and our invention,broadly stated, consists of the above arrangement of parts and ofcertain other novel details of arrangement and con-' struction that willbe hereinafter described, and setforth in the claims.

In order that our invention may be-fully understood we will proceed todescribe the same with reference to the accompanying drawings, in which-Figure 1 is a perspective view of a wagon having our invention appliedthereto. Fig. 2 is a perspective view of the front body-bolster havingthe divided axle journaled thereto. Fig. 3 is a perspective View of therear body-bolster and divided axle. Fig. 4 is a de tached perspectiveview of the divided axle and other parts connected therewith. Fig. 5 isa detail sectional view. 1

In the said drawings, 1 represents the reach of the running-gear of awagon connecting the front bolster 2 and the rear body-bolster To thefront and rear bolsters we journal the divided axle or separate axles,if preferred, on which the wheels are journaled. The same arrangement ofaxle is provided for on the front and rear bolsters, and a descriptionof one will therefore suffice for both.

4 and 5 represent the two parts of the axle, and they are j ournaled tothe bolsters by means of the hangers 6, at the ends of the bolsters, andthe central hanger 7. The ends of the axles fitting in the hanger 7 areformed with a groove 8, in which the set-screws 9 fit Serial No.631,660. (No model.)

in order to hold the ends in the hanger. The outer ends of the axle areformed with the cranks 10, on which the wheels are journaled.

11 represent arms fixed to the axles 4: and

5 by means of the feather 12, which fits in load is on the wagon,between the projections.

The rods 16 extend through openings 18 in the bolsters, and they areheld by means of springs 19, which fit between the washers 2O and 21 onthe rod. The washer 21 is held by means of the nut 22, working on thescrewthreaded end of the rod.

From the above description it will be observed that each wheel is heldby means of a spring, so that when the wheel rides any obstruction orunevenness the spring will'prevent any tilting or jarring of thewagon-body.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-- '1. In awagon, the combination of thebodybolsters the divided axles, the end and central hangers fixed tosaid bolsters in which the axles are journaled, grooves formed in theends of the axle fitting in the center hanger, set-screws fitting insaid grooves, and suitable means for yieldingly connecting the axle withthe body-bolsters, substantially as shown and described.

2. In a wagon, the combination of the bodybolsters the divided axlesjournaled thereto, arms fixed on each section of said axles and havingprojections at its upper end which are provided with openings, rodshaving one of their ends held between said projections, and their otherends passed through the'body-bolster, and springs on said ends betweenthe body-bolster and the free ends of the rods, substantially as shownand described.
